P'AINI-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 280,696, dated July 3, 1883.

Application filed March 19, 1883.

,To aZZ whom it may concern .clear, and exact description of 'theinvention,

such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in that class of paint-distributers in which the operative mechanism is driven by a current of air, and the paint is distributed by the joint action of a rapidly-moving reciprocating needle and said current of air, the construction and operation of which classes of paint-distributers are fully illustrated and described in the United States Letters Patent No. 256, 852, which were granted on the 25th day of April, 1882.

My improvements consist in the peculiar construction of a needle and the device by which it is operated. a

Heretofore the paint-distributing needle has been operated by a crank, with which it was connected at its rear end only with the windwheel, in which case it became necessary to use a heavy large needle, that the same might have sufficient rigidity to be controlled and operated from its rear end only, and in certain classes of work I have .found that it becomes necessary to use a much finer needle for distributing the .paint than could be practically used when the needle is thus supported only at its rear end. My invention is further explained by reference to the accompanying drawings, in which Figure 1 represents a top view of my improved needle as connected with the operative Fig. 2 represents a side view,

and Fig. 3 a detail of the same.

Like parts are represented by the similar reference-letters throughout the several views. A is a wind-wheel, which is adapted to be. operated by a current of air conducted thereto by a small tube, as shown in said Letters Patent.

lModel.)

B is a paint-trough, in which a small quanrear end only, in which case none but a large heavy needle could be used. By my improvement the needle is supported at both its front and rear ends by retaining-bow F, by which bow I am enabled to use a very fine, flexible wire, as it is held taut by the bow and pre vented from bending or vibrating. The bow F is preferably formed in asingle piece, which is attached to the crank-E by hinge G, which hinge permits said crank to perform a circular movement as the wind-wheel revolves. The lower arm, H, of the bow operates in a guide-groove, I. The armHis retainedinthe groove I by aretaining-button, J. Thelower end of the tube 0 is moved over the places where it is desirous to distribute the paint, while the needle D is caused to reciprocate rap idly beneath said tube. As the needle reciprocates, a small quantity of paintis carried forward with each forward movement of the same beneath the lower end of said tube 0. \Vhen the current of air escapes from said tube, the paint is blown from said needle and uniformly distributed on the canvas. The needle D is, for the purpose intended, necessarily formed of a slender, delicate wire incapable of sustaining its own weight when supported at one end only. When, however, it is thus attached at its respective ends to the bow F, it is retained in a rigid, taut condition, and is prevented from swaying and bending, whereby much finer and more accurate work may be done than it would be possible to do by the needles as heretofore constructed and operated.

Having thus described myinvention, I make no claim herein to the wind-wheel, air-tubes,

IOO

paint-trough, or the other parts ofthe operative mechanism of the machine separately considered; but

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. The combination of painttrough 1'3, with the distributing-needle 1), formed of a slender wire, with a supporting-bow, F, said bow being adapted to support said needle at its re spective ends, whereby it is held taut and prevented from bending, substantially as and for the purpose specified.

2. The combination of the needle I), bow F, said bow being adapted to support said needle at its respective ends, crank E, and wind-wheel A, as set forth.

3. The combination of bow F, needle I), as I attached at its respective ends to said how, crank E, and guide-trough T, substantially as and for the purpose specified.

.4. The combinationot'bowF, providedwith arm H, needle I), guide-grooves I, crank E, and wind-wheel A, said arm 11 being adapted to operate in said guide-grooves I, whereby said needle is guided and retainedin its proper position beneath the tube 0, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
